UNITED STATES AUGUST H OPPER'MAN, OF INDIANAPOLIS, INDIANA.

ELECTRICAL GURLING-IRDN HEATER.

Application filed July 25,

To all whom it may concern Be it known that I, AUGUsT H. Orrna- MAN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Electrical Curling-Iron Heater, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to an improved heater constructed so as to be portable and to be electrically heated, the invention having reference more particularly to a heater that is particularly adapted for heating curling-irons or other articles.

An object oft-he invention is to provide an electric heater which shall be so con structed as to be convenient for use for various purposes when moderate heating is desired, and which may be safely placed and used on tables or other furniture without injury thereto.

Another object is to provide an improved electrical heater which shall be so constructed as to be adapted for heating articles in the interior thereof and also other articles on the outer side of the heater.

A further object is to provide an improved electric heater which shall be of simple design and few parts permitting inexpensive construction, which shall be durable and economical in use, and which maybe readily repaired at small cost if necessary. a

A still further object is to provide an improved hollow electric heater which shall have a combined shelf and shield on which to temporarily place heated articles.

With the above-mentioned and other objects in view, the invention consists in a structurally improved electric oven adapted to apply heat both internally and externally; and, the invention consists also further in the novel parts and combinations and I arrangements of parts as hereinafter particularly described and further defined in the claims appended hereto.

Referring to the drawings,Figure 1 is a side elevation of the improved heater as preferably constructed; Fig. 2 is a longitudinal vertical central section of the heater; Fig. 3 is a. fragmentary transverse section of the heater; and, Fig. 4 is a fragmentary side view partially in section showing details and a modification of the oven structure.

In the difierent figures of the drawings lees. Serial No. 653,763.

similar reference characters indicate corresponding elements or features of construction herein referred to in detail.

As preferably constructed the improved heater comprises a slab-shaped base 1 which preferably is oblong in plan and anon-metallic poor conductor of heat to guard against injury to furniture upon which it may be placed, and the base has two recesses 9 and 8 extending upward from the under side thereof, and also a similarly arranged chamber 4: adjacent to one end of the base, the upper portion of the base having an aperture 5 therein extending from the chamher to the top of the base, the base having also a horizontal aperture 6 extending from the chamber to the adjacent end of the base. Preferably a suit-able pad 7 is secured to the bottom of the base and closes the lower ends of the. recesses and the chamber, the pad preferably being composed of felt or other material tending to deaden sounds and to prevent the base from causing scratches on fine furniture, the pad being a non-conductor of heat.

The heater being provided with a device for holding heated articles, the device preferably is arranged at a suitable distance above the base, and for this purpose the top of the base has two small hollow posts 8 and 9 arranged thereon above the recesses 2 and 3 respectively, and a pan 10 is arranged thereon so as to support articles thereon, the top of the pan being concave to deflect heat upwardly and preferably having slightly upturned edge portions 11 and 12, the ends of the pan having stiffening beads 13 and 14 respectively formed of metal turned under the bottom of the pan. Adjacent to one end of the pan the transversely middle portion thereof has an aperture 15 in which a tube 16 is connected that rests upon the top of the base so as to extend about the top of the aperture 5. A center bar 17 preferably is arranged upon the pan and is nearly as long as the pan, the lower portion of the bar having screw-threaded holes 18 and 19 therein receiving screws 20 and 21 that are inserted through the recesses 2 and 3 respectively and extend through the posts 8 and 9 respectively and also through suitable holes in the pan, the screws having heads 22 and 23 respectively that are seated in the recesses. This arrangement pro vides two shelves separated by the bar 17 and separated also from the base, upon which two' curling-irons maybe placed-after having been heated and kept separated by the center bar 17. The center bar has a pillar 2% adjacent to one endthereotwhich has 5 a cavity 25 therein extending upward from the bottom of the bar, the pillar having an inclined top 26. The center bar has also a hollow stand 27 adjacent to the opposite end thereof, the stand having an inclined top 28 corresponding in inclination to the top 26,

the stand being less in height than the pillar 24, and it a chamber 29 that incloses the upper end of the tube 16, the top 28 ha"- illga channel 30 therein extending from the chamber to the upper face of the top.

' The even portion of the heater comprises a hollow cylinder orshell 31 thatis arranged upon the inclined tops 26 and 28, the cylinder having'an annular head fittingclosely in its higher end provided initslower portion with a screw-threaded hole 33. The oppositeend of the. cylinder orshell has an annular head 23% secured therein, or in some cases a solid head 3 as shown in 4, the 25 under portion of the headhavinga screwthrea ded hole 35 therein; ScrewsBS and 37 are arranged in the inclined-tops 26 and 28 respectively and extend into suitable. openings in the under side of the wall of the 30 cylinder and into theholes' 33 and 35 rc spectively, thescrew 36' having a head 38 arrangedinthe recess 25, the screw having a head 89 arranged in the chamber :;terial are-arranged within the cylinder or hell achaeentto the inner sides of the two heads respectively and a'hollow core 42 is placed upon the shelves'to cool and without the-danger of"injuring turniture or garments as may occur when there happens to "be no convenient-place for the used but still of the spacers,a hollow core supportedfat 'cured'to' the base and supporting the shell,
